can you provide a repro mission? is this a mission you've made or downloaded?

This is a Campaign mission. When you are in the camp. Topolia for example.

so please change your ticket category to one of the campaign issues ("Campaign Episode x: "), and update your description to reflect what this issue is for and where...vague descriptions help nobody

I can't see a difference between the two uploaded pictures; both have the same light at the briefing table.

It might be a graphics/monitor setting issue, or it simply overblends the existing light.

@Fireball the pictures are just of his graphics settings, I believe
check the video for the actual bug

Which campaign episode is that?
